content is empty

Error message

content is empty

What it means

A post-read content guard in the tree-summarizer ingest subcommand: content was resolved (from `--content`, `--file`, or stdin) but the resulting string is empty. This fires when the user passes `--content ""`, points `--file` at a zero-byte file, or pipes an empty stream — there is nothing to summarize, so the tool refuses rather than producing a degenerate summary tree.

Solutions

1. Check the input actually contains text: `wc -c <file>` to confirm it is not zero bytes
2. If reading from stdin, confirm the upstream command produced output
3. Trim only whitespace-padded input — a string of just whitespace still counts as empty here
